J 'actjautomatically, iu'ndeimanual control from I I a distant point, toplace the skate on a track 'rail in its operative position. "The presentI invention relates to such a skate machine;v

In accordance with the presentinvention,

' it'isjproposed to provid'e a skatemachine,

o power-operated and manually controllable from distant point, in whichtheskate: is supported and carried in sucha way by the 7 machine that itcan be placed on the rail in itsactive position, or removedfrom therail, so that the skate machine may be tested whenever desired. A1so,-itis proposed Ito provide an operating connection to the skate insuch awaythatthe skate maybe engaged by a car wheel and carried away from thevskate1nachine,.,eve1rthough-the skate may "have beenin its operatedposition and with goutdamage .toiit; More specifically, it is-proposed-to provide-hanfoperative,but dey 1 t'achable, connectionbetween'the skate and a 40 power-operated holder,this connection in thespecific form. illustrated being'made in the ,vformio'f a keyedortapered'dove-tailed con- .i struction.

mortise. which widens out inwardly to accommodate the tapered key ortenon project ing from the skate placing member 5l1eretofore described,the shape of this key and the counter part thereof being readily 1understood from the illustrations shown in Figs. 3 and 4.

By looking in Figs. 2 and 3 it readily appears that the turning of shaft6 causes the skate placing member 5. and the skate detaehably connectedthereto, to be moved from one position to the other. And in order toavoid the motive power mechanism for operating this skate being damagedin the event the skate should fail to disengage from its holder when acar rides thereon and carries the skatewith it, or in the event the cartruck is entirely derailed when it strikes the skate, the motive powermechanism iseprefe "ably located some distance from the skate, andpreferably toward the left, that is to the rear of the skate placingmember as shown inFig. 1. In accordance with the present invention theshaft 6 is connected to a socket member 20 by a universal joint 21constructed in the usual way, this'so'cket member 20 being provided "ithasquare hole into which the square shaft 22 snugly fits, the other endof this squared shaft being connected by the universal joint 23 to theoperating shaft 24.

of tlfe inotivepower mechanism contained in the casing 25. This shaft 2%having contained thereon a yoke 27 forming a pair of lever arms betweenwhich is pivoted an operalting' bar 538 by a am 29. It thus readilyappears that if the ar 28 is operated back and forth that the skate S isoperated from its normal position, in which 'it lies on the stop or restplate 30, to its active position on therail and back again. y

If new; the skate is moved to its active position; as shown in Fig. 3,the passage of a car moving from left to right causes its left liafndfront wheel to ride on theskate S thus caiising the skate to slidealongon the rail 1 and in so doing disengage from .theskhte placingmember 5. and due to the additional friction injected,by the sliding ofthe first wheels and axle, causes the. car to be brought to a stop. Inthe event, however, that the passage of a car in carrying the skate withit causes binding engagement be tween the skate and the member 5 andcarries the member 5 together with the support with it, no damage islikely to be done to the motive power mechanism by reason of the slidingengagement between the skate member 20 and the square shaft 22. Also,sincethe skate placing member is located toare the right of the motivepower mocha nism the apparatus carried by the car wheels is carried awayfrom and not toward the motive power mechanism. 7

In order to simplify the drawings and de scription of the particularform of theinvention illustratednospecific means for operating theoperating bar 28 has been shown.

It isyhowever, desired to be understood that the motive power casing 525may contain suitable electrically operated means whereby the bar 28 maybe reciprooated or may contain suitable pneumatica lly operated or fluidpressure operated mechanism for operating the bar 28 1n one direetion orthe other as condit1ons require. Also,-that the motive power mechanismin casing 25 maybe controlled from the operators tower at some distancefrom the skate machine. The tapered key or dove tailed detachableconneetion between the skate placing member 5 and the skate S ispreferably such-as to 'eonstitale a rather loose fitting: connection;this" in order to avoid binClingl)etwee11 the memher 5 and the skate Sas the skate is dragged off by a passing car. Also, itis desired topointont that the taper of the key is such as to materially lessen thedanger of binding between these two devices upon endwis movement of theskate S. 1

The particular embodiment of the invert when the skate ismovedlongitudinally on the track rail, it is desired tobe understood that theparticular arrangement"shown and described has been illustratedfor thepun pose of facilitating the(lBSCI'lPtlOI'lfOf the invention and notwith the idea of illustrating the specific constructionpreferablyemployed in practicing the intention nor with the idea ofillustrating the scope of the invention, and that various changes,modifications and adaptations may be made without departing from thescope of the invention or the idea of means forcarrying out suchinvention.
